What does whiz mean?
Whiz is an informal English word best known as a noun for a person who is exceptionally talented, knowledgeable, or quick at a particular activity. Saying that someone is a 'whiz at languages,' for example, presents that ability admiringly, although the word can sometimes imply narrow or showy technical proficiency. Whiz can also function as a verb meaning to move very quickly, as in 'the car whizzed past,' where the word evokes speed and a rushing or buzzing sensation. As a noun, it can additionally refer to a quick movement or the sound associated with one. The word is common in both British and American English, though 'whizz' is also widely used as a spelling variant. Although the expert sense is strongly associated with informal speech, it remains familiar in journalism, education, and descriptions of technical ability. Whiz is especially useful because it combines a person's competence with an impression of speed, sharpness, and energetic performance.

Where does whiz come from?
The modern noun meaning 'an expert' developed in early twentieth-century English as an alteration of wizard, using the older figurative sense of a wise or exceptionally learned person. Wizard, wise, wisdom, and wit are related through the Germanic and Indo-European roots associated with knowledge, understanding, and discernment. The verb and sound-related senses developed alongside the expressive rapid sound represented by whizz, which also became a spelling variant of the word.
